Further glaucolides and other sesquiterpene lactones from Brocchia cinerea

The reinvestigation of the aerial parts of Brocchia cinerea ( = Cotula cinerea) afforded in addition to several known sesquiterpene lactones two new eudesmanolides, five guaianolides and seven glaucolides, three of them with an eudesmane skeleton and four with a germacrane skeleton. The structures w...

Summary:The reinvestigation of the aerial parts of Brocchia cinerea ( = Cotula cinerea) afforded in addition to several known sesquiterpene lactones two new eudesmanolides, five guaianolides and seven glaucolides, three of them with an eudesmane skeleton and four with a germacrane skeleton. The structures were elucidated by high field NMR techniques.
